According to Wikipedia, in April 2008, the number of videos on Youtube was 83.4 million (ref: http://en.wikipedia.org/wiki/YouTube#cite_note-5). However, the link in the cite note now displays “*” video results 1 – 20 of millions, without showing the real count.

Here's one way I found to get an estimated, but relatively accurate, number of videos on the popular video sharing site Youtube. The idea is simple. Get this feed: http://gdata.youtube.com/feeds/api/videos/-/* and parse out the number inside the &lt;opensearch:totalresults&gt; tag.

So here it is: the number of videos on Youtube is currently fluctuating between about 141 million and 144 million. The number goes up and down, which points to the fact that these are estimates.

If you haven't heard of Digsby yet, you have probably been living in some kind of a virtual cave or have no friends. Digsby is a multi-network instant messenger application, similar to Trillian, Pidgin (GAIM), or Miranda. I said 'similar', so what makes Digsy special? Reviews I read so far don't give the real reasons and don't dive into the features in depth. Instead, you get a standard load of marketing BS and in the end to you, the user, Digsby may end up being "yet another IM program." Some reviews describe certain features, but so far I haven't seen one that highlighted THE MAIN REASON why Digsby is different. And may I preface it with: finally somebody got a …

I want to get opinions from outside of my daily circle of people on the best server hardware to use for MySQL. I remember from the conference somebody (Pipes?) mentioning a particular Dell server with multiple disk RAID10 that could supposedly be had for about $6k but I completely misplaced the model number (Frank, did you get my email?).

I know that a multi-disk RAID array with a bunch of fast disks (15k RPM?) is probably the most important method of improving performance, followed by the amount of RAM, so I'm trying to find the best combination/balance of the two. However, server prices on the Internet range so much that I don't even know where to begin to tell a …

I think this is going to be really neat: you walk around the streets of San Francisco, for example, with your Android powered phone, en route to your destination 20 blocks away.

You whip out your phone, go to Google Maps, pull up the StreetView (remember this?), which zeroes in on your location using a built-in GPS, and then changes as you move the phone around using the built-in compass.

You then virtually walk the city, looking around, without actually moving an inch (looking for the closest ATM, restaurant, etc, hint-hint?).

Recently I ran into major problems using GNU diff. It would crash with "diff: memory exhausted" after only a few minutes trying to process the differences between a couple 4.5GB files. Even a beefy box with 9GB of RAM would run out of it in minutes.

There is a different solution, however, that is not dependent on file sizes. Enter rdiff – rsync's backbone. You can read about it here: http://en.wikipedia.org/wiki/Rsync (search for rdiff).

The upsides of rdiff are:

with the same 4.5GB files, rdiff only ate about 66MB of RAM and scaled very well. It never crashed to date.

it is also MUCH faster than diff.

rdiff itself combines both diff and patch capabilities, so you can create deltas

One thing that still springs to mind when I think of the MySQL User Conference last week is Sun's opening keynote. While talking about Sun's market penetration with open source software, Jonathan Schwartz, Sun's CEO, slipped in a short mention of the mobile market saying something along the lines of "Sun is going to be entering the mobile market later on this year". He didn't spend more than 5 seconds talking about it, moving on to the acquisition of MySQL.

Last year, Sun already made an announcement of JavaFX, a Java-based mobile platform but didn't provide any concrete timelines, so I was excited to hear the more on the subject. With Apple iPhone's advent last year and …

Unfortunately I didn't find any available seats to take notes for this but this morning a very interesting keynote took place. Representatives from 7 large companies mentioned in the title gathered on stage and answered various questions by MySQL's Kaj Arno.

These questions included things like "how many MySQL servers do you have", "how many DBAs", etc. It was a lot of fun, hopefully someone (Sheeri) will edit and post the video soon.

Keith has a nice summary of everything that went on together with the numbers here.
